DS2 was always quite little (25th centile) but recently I realized he was just not growing out of his clothes any more. I haven't had him weighed for ages I once I went back to work I couldn't get to the health visitor's clinic, so I arranged to take him into the surgery to weigh him properly and was rather horrified to find he has dropped to the 2nd centile in the last 6 months.
Apart from his weight his development generally seems fine which is why I hadn't worried too much before, but now I find we're being referred for blood tests etc. He has had an awful lot of minor bugs (especially tummy bugs) since starting nursery before Christmas, but we thought that was just normal (DS1 was the same - though it was ear infections and colds with him). Now I am really worried there might be something wrong and I should have done something about it earlier.
Does anyone have experience of anything similar? What could be wrong? I don't even know what might cause this.
